If there’s a plasma donation center in your area, you might be able to make anywhere from $25 to $50, and odds are, you’ll get paid today. Call ahead and ask, of course, but these days, many donation centers are giving money cards (similar to a debit card). Generally, it takes about 30 minutes to donate your plasma, but a first visit may take longer — up to two hours — since you’ll be filling out paperwork and taking a physical. And while it’s not a ton of money, many donors are able to sell plasma twice a week.
Sell scavenged valuables. If you have a metal detector, or even just a good eye, go to public places where people are likely to drop something unnoticed (such as parks, beaches, and shopping areas), and look for money, jewelry and other valuable goods. This method isn’t very reliable, but you just might get lucky and be able to find something you can sell quickly for cash.
This may sound like a dumb idea, frankly, but a lot of banks these days are offering $200 to $300 signup bonuses to customers who open up a new checking account. The catch, though, is that you generally have to really open these accounts. You need to be willing to set up a direct deposit and put money in the account, and you often don’t receive the bonus for at least a month, sometimes even longer. On the other hand, if you were thinking of going to a new bank, anyway, it’s an easy way to make some extra cash.
While publishing an ebook on Kindle isn’t the easiest way to make money, it can be a worthwhile way to make some extra cash if you love writing. You can create listicle books like ‘100 Ways to Save for a House.’ Listicles are generally easier to write and can be effective at driving traffic. To market your ebook, you can take advantage of Amazon’s Kindle Countdown Deals promotions where you can give your ebook away for free to help boost its ranking on the platform. Once the promotion is over, you can likely get a few sales from its higher rank. You can also promote your ebook on several platforms like ebook review websites and relevant niche blogs. To boost sales even more, you can create an audiobook version of your ebook on Audible.
Become a freelance writer or editor. If you have a passion for storytelling or a background in writing or editing, it’s possible to find freelance writing or editing work online. To search available job openings, check out sites like UpWork.com and Problogger.net. You can also check traditional job sites such as Indeed.com and enter “telecommute” or “anywhere” in the location field.

Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.

Even in the age of automation, some jobs still require a human touch. Companies often outsource those jobs via services like Amazon’s Mechanical Turk. These jobs can be tedious — tagging images, transcribing videos, classifying receipts — and can take anywhere from a few minutes to a few hours. Pay depends on the task, and the person requesting the work gets to approve the finished product before paying you. That can leave room for scams, so do your research and join a community like TurkNation, which can steer you away from shifty dealers. Read more about doing tasks on Mechanical Turk.
Be proactive. Remember Murphy's Law: "Whatever can go wrong will go wrong." Make plans, complete with as many calculations as possible, then anticipate everything that can go wrong. Then make contingency or backup plans for each scenario. Don't leave anything to luck. If you're writing a business plan, for example, do your best to estimate when you'll break even, then multiply that time frame by three to get a more realistic date; and after you've identified all the costs, add 20% to that for costs that will come up that you didn't anticipate. Your best defense against Murphy's law is to assume the worst, and brace yourself. An appropriate amount of insurance may be something worth considering. Don't forget the advice of Louis Pasteur, a French chemist who made several incredible breakthroughs in the causes and prevention of disease: "Luck favors the prepared mind."
26. Services – You can offer a paid service, such as life coaching, blog coaching, goal setting or financial planning. Just be sure to investigate all the legal implications and make sure you’re not claiming to be a professional if you’re not one. With a service like this, you’re basically using your blog to sell yourself. You’ll need to convince people that you’re worth buying and then be able to back up your claims once they purchase your service.
Recognize that time is money. This critical piece of advice is attributed to Benjamin Franklin, who was an accomplished American inventor, journalist, printer, diplomat, and statesman--the ultimate multitasker. Your ability to manage your time (and stop procrastinating) is a critical ingredient in your ability to make money. Whether you have a job or are self-employed, keep track of what you're spending your time on. Ask yourself "Which of these activities make the most money, and which of them are a waste of time?" Do more of the former and less of the latter, simple as that. When you're focusing on high-priority tasks, get the job done well, and get the job done fast. By working efficiently, you're giving your employer or clients more time, and they'll appreciate you for it. Remember that time is a limited resource that you're always investing. Will your investments pay off?
Ask your parents if they'll pay you for doing more chores. You're probably already expected to do chores around the house and help out your family for free. If you need a little extra pocket change, however, ask your parents if there's something else you can do for a small fee. For instance, maybe your mom really hates folding laundry and would be willing to pay $5 a week for you to do it instead. Whatever it is, let your parents know you're willing to take on more work for a bit of allowance.
Become a babysitter. Babysitting is a common way to make some extra money on the side.[26] There are now professional services you can sign up for that will connect you with people who need a babysitter. For these services, it will help to pass a CPR class or other certification, or to have a talent or expertise for entertaining children. However, you might be able to make money more quickly just by babysitting for people you know, or by having friends refer you to others who need a babysitter.

Seek a payday loan or title loan as a last resort. Companies that offer payday and title loan services are commonly available, and can be a way of making quick cash. However, these typically offer extremely high interest rates (sometimes with percentages in the hundreds). If you cannot pay the loan and any interest back within the stated timeline, you risk even higher interest costs or, in the case of a title loan, the loss of your car. Avoid these types of loans in all but the most dire circumstances, unless you are certain you will be able to pay the loan back.

Yes, I went to bartending school after I graduated from college. When I didn’t get any job interviews, and my meager savings were drying up I needed a quick solution to make money for the rent. Five days later and $495 lighter, I graduated bartending school. I never poured a drink – I found a programming job the same week I was supposed to start bartending at a golf club.
